If you thought Tavi Gevinson was young, meet Mayhem. In just under a year, the 4-year-old phenom has amassed over 375,000 followers on her mother Angie’s Instagram (@2sisters_angie) feed, and countless millions of “likes” for her construction paper–versions of red carpet looks—from the crimson-caped Ralph Lauren moment for Lupita Nyong’o at the Golden Globes to the Valentino music note confection Katy Perry wore at the Grammys, with the odd Minnie Mouse getup or Frozen coronation outfit thrown in for good measure.

“It started in a spare room that used to be my office,” Angie says via phone from Atlanta, where she is attending a social media conference called the Mom 2.0 Summit. “Now it’s our design studio.” It’s also the carpeted space where Mayhem models her DIY creations. It’s not Milk Studios (the “set” is gossamer drapes and adjacent beige sofa), but at this point the minimalist backdrop is all but an Instagram meme. And Mayhem herself is proving to be something of a supermodel in miniature. So far, the precocious toddler has mastered the classic movie star hand-on-hip (after Jennifer Lawrence, on a January 13 Instagram post), the “I live for fash-shun” projected shoulders and elbows (August 27, 2013), and even the Arthur Elgort jump, an iconic Vogue pose if there ever were one (February 25).

Perhaps the most remarkable aspect of Mayhem’s steady rise to Internet fame is that her mother never followed fashion news before Mayhem—a nom de plume adopted from those Dean Winters Allstate commercials—took notice of the dresses that popped up on Angie’s newsfeed. “I had absolutely no idea what I was doing,” Angie says. And while Mayhem herself was unavailable for comment during our phone call—an important session with a swing set took precedence—she later accredited her newfound fashion erudition with typical insouciance. “I just learned it up,” Mayhem says.
